V-VAl//1`VA INVENTPR i I.May 29,v 1928.

" Appunti aiea'lvember as, me. semi at.' 150,935. i

The intention relates to devices readily 3 applicableu n various forms of work for correctly an easily determining the centers therein and for marking points remote from the centers thereof.

Another object of the invention resides in the construction of supportin` means consisting of thrust arms' adapted5 to be moved outwardly for engagement with the. work and an arm connected with the centered axis l which in turn ma berelatively4 adjusted for punch marking t e work at a remote'point rom the 'centen thereof.

An additional ...object of the invention comprehends a' pointer adapted -for rotary movement uponthe vdevice to clear] determine punch marking of work, if desired and pre-determined distances therefrom.l

With theabove and other objects in view, the invention further includes the following `novel features and details of construction, to-

rbe hereinafter more fully described, illustrated in the accompanyin 'drawings and pointed out in the appende claims.

In the drawings Figure 1 is a top plan view of the inven-- tion. Y l

- Figure 2 is a bottom plan view thereof.

A Fi ure 3 is a transverse section ltaken on the line 3-3 of Figure 1.

Figure 4 is a similar view 'of the adapting or centering means per se. v

Figure is a similar view of the range finding adjusting means.

` Figure 6 is a sectional view taken on the line 6--6 of Figure 1.

.Fi ure 7 is a vertical section takenon the line -7 of Figure 4.

v Figure 8 is a etail perspective of a thrust arm.

' Referring to the drawings in detail wherein like characters of reference denote v. corresponding '.parts, the reference character 10 indicates' a relatively flat disk member having semi-circular rooved portions 11 ex- -tending from near t e center thereof and within which are positionedfor travelling movement downwardly extending studs 12 carried upon the underA sides of the thrust arms 13 which also provide offset end portions 14 for seating and supporting the device in its entirety upon the periphery of an opening. Such thrust arms 13 are guided between spaced lu members 15 depending -from the under si e of a disk 16 varrange Ain superimposed relation with the disk 10;

the upper -portion of the 'bore thereof while an en arged and aperboth of which receive the lof-wer end of a verrA'rENr OFI-fica.

tically disposed adjusting in 17 received centrally thereof and wit in av spacing washer 18 arranged between the correspond ing inner Vsides while the upper and outer end of the pin has a central or knurled portion 19 to provide convenient gripping means thereon to facilitate andimpart the necessary thrust to the arms 13.

As mentioned in the foregoing, the inv ention is adapted for application upon varions forms and designs of \vork, but in this instance is applied u on a'^cylinder block 20 and fitted over an upon the bore 21 thereof in the manner as. illustrated in Figures 3 and 4 of the drawings. An upwardly extending exteriorly threaded sleeve portion 22 inte rally formed and centrally dis osed upon t e upper side of a calibrated an apertured disk 23 adapted to receive tured circular portion 24 is received an loosely mounted upon the outer surface of.

in 17 Within the I sov the sleeve 22 and has a ointer hand 25 provided upon one side w ile spaced parallel relatively fiat arms 26 radiate in diagonally disposed relation therefrom with respect toA the pointer hand 25. A gauge plate 27 is provided having channels'28 formed in its opposite side edges which channels are adapted to receive therein the adjacent edges of the arms 26 for slidable connection therej with. Said plate has marks formed thereon ada ted to be brought into registration with cali rations upon the upper sides of the arms 26 in order that a in 29 may be dropped within any one o a plurality of openings 30 inthe face of the calibrated disk 23. A punch pin 31 carried by .the

late 27 may afterwards be tapped by a animer or like instrument to indicate a desired point remote froml the center of the work. A. knurled nut 32 is threaded upon the outer side walls of the upwardly extending exteriorly threaded sleeve 22 to sustain the pointer hand 25 and a'rrns 26 upon the face of the disk 23 and for'rigidly locking the saine in place to servel as an auxiliary to thepin 29 in the instance of a finer adjustment than that afforded by the pointer hand 25 or the,Y pin 29 ada ted for reception within the openings'30 of t e disk 23.

It will be noted from the foregoing description that rotary movement imparted to the disk 10 due to the fixed connection of ico .inder bloc As illustrated in' Figure 5j of tli'e draw-` ings, the su The inventionvis primarily adaptedmfor use upon g: rs vand internal combustion cylrstructureof the invention utilizes the disk 23 as lthe base and mayl vbe -usedindependntly ofthe disk lrandsupL porting arms 14g inthe instance of its application u on flat-work. The vpin li'` is also lacking. in so far as a punch pin issubstituted .therefor to indicate the centerof the-v work to be laid out. '4

' The invention is'susceptible lof variousf' chan es in its form, proportions and'ininorf detai s of construction and the right is 'hereinreserved to make sii'cli 'changes as prop erly fall withinftlie scope of tlie appended claims.

Havin claimed is: I

1. A lay outdevice comprijngj superimposed disk members, means for` connecting said disk members for relative rotation, arms slidably mounted between the disks, means whereby rotati'on to one of. the disks may be imparted, saidl arms having connection with the rotatable disk and adapted to be shifted simultaneously with the rotation of the disk, a punch, means adjustably supporting the punch with relation to' the disks, and 'the remaining disk being adapted to limittheshiftin movement of the arms.'

2. A lay out evice comprising disk members', `4 means fof connecting said' disk-- mem i' bers for relative rotation, supporting'arms' slidably Yarran'gedbetween the disks, one of "the disks having grooves, studs -carried by the arms and vpositioned withintlie'grooves ,and adapted to be shifted 'upon-rotation of the aforementioned-disk, and the remaining" disk being adapted to retain the armsin,

position'for use.;l l

3. Aflay out its peripher ,I a seconddisk arranged be.-

rooves'therein, means `for connecting -sai isks'` for relative rotation, lurnifs" slidably mountedJbet-ween the 'disks j and provided with studs Aextended within the grooves for laterally* shifting the arms upon rotary. movement imparted vto the' disks, a pin carried by' thel grooved disk to correctly deterl mine a'measurement remote from the center 'described 'the inventionV what` isv ofthe disks.

4. A Alay out device. comprising `sup'erimf device compri-sing a vfdisk liavingspacedv annular series of lopenings therein, Aand graduations alonga portion of posed disk members, means for connecting said disk' members. for relative rotation,

arms. slidably mounted between the disks,

means centrally disposed of the disks where by movement to one of the disks may be imparted and arms to dispose the device cenerv trally of the work upon which the same is applied and the' remaining disk bein adapted to check the shifting movement o the arms. .l s t In testimony whereof .I aiiixlmyy signature Louis J.
